EXHIBIT 10.2

                     MASTER LEASE AND DISTRIBUTION AGREEMENT


         THIS MASTER LEASE AND DISTRIBUTION AGREEMENT is effective as of the 1st
day of August, 1996, notwithstanding the actual date of execution, by and
between THE VALVOLINE COMPANY, a division of ASHLAND INC., a Kentucky
corporation, with offices located at 3499 Dabney Drive, Lexington, Kentucky
40509 (hereinafter referred to as "Valvoline"). FIRST RECOVERY, a division of
Ecogard, Inc., a Delaware corporation, with offices located at 3499 Dabney
Drive, Lexington, Kentucky 40509 (hereinafter referred to as "First Recovery"),
and MANSUR INDUSTRIES, INC., a Florida corporation, with offices located at 8425
S.W. 129 Terrace, Miami, Florida 33156 (hereinafter referred to as "Mansur").

         WHEREAS,  Mansur has developed and patented a recycling parts washer 
under U.S. Patents No. 5,349,974 and 5,388,601, and has other patents pending
with respect to such machinery, more particularly defined below as "the
Equipment"; and

         WHEREAS, Valvoline desires that First Recovery shall obtain certain
rights to distribute the Equipment, subject to and in accordance with the
provisions hereof:

         WHEREAS, Valvoline and First Recovery have represented to Mansur that
First Recovery has the ability, experience and resources to market and
distribute the Equipment on a national basis; and

         WHEREAS, the parties desire to enter into a pilot program to evaluate
the market for and performance of the Equipment and First Recovery's ability to
market and distribute the Equipment, which program may provide the basis for the
parties to enter into a broader, longer term agreement, subject to negotiation
of a mutually acceptable agreement.

         NOW, THEREFORE, in consideration of the foregoing premises, the mutual
covenants, agreements and conditions hereinafter set forth and the mutual 
benefits to be derived therefrom, the sufficiency and adequacy of which is
hereby acknowledged, First Recovery and Mansur hereby agree as follows:

         1.       SCOPE OF SERVICE

                  1.1    Subject to the terms and conditions hereof, including
without limitation, the early termination provisions hereof, during the Term (as
defined in Paragraph 2 hereof), Mansur shall lease to First Recovery one
thousand (1,000) recycling parts washer units, which units are more particularly
identified in Exhibit A to this Agreement, attached hereto and incorporated
herein by reference (the "Equipment"), on the schedule set forth herein. All
Equipment will carry the manufacturer's warranty specified herein.






                  1.2    During the second and third month of the Term, Mansur
shall lease to First Recovery one hundred (100) units of Equipment, at the rate
of fifty units each month (the one hundred (100) units are hereinafter referred
to as "the Initial Inventory"). In First Recovery's sole discretion, the Initial
Inventory of Equipment may be used by First Recovery for free trial placements
at potential customer locations as a marketing tool to secure customer leases of
the Equipment, or may be leased by First Recovery to its customers. First
Recovery shall use its reasonable and best efforts to solicit customers in the
Territory, (as defined in Paragraph 4 hereof), to lease Equipment.

                  1.3    During the fourth and fifth month of the Term, Mansur
shall lease to First Recovery one hundred (100) units of Equipment, at the rate
of fifty (50) units each month. During the sixth through thirteenth month of the
Term, Mansur shall lease to First Recovery and aggregate of eight hundred (800)
units of Equipment, at the rate of one hundred (100) units each month.

                  1.4    The Initial Inventory shall be leased to First Recovery
at the reduced monthly rates specified for Initial Inventory outlined on Exhibit
B, attached hereto and incorporated herein by reference, and all other units of
Equipment to be leased hereunder during the Term shall be leased to First
Recovery at the standard monthly rates specified in such Exhibit B. All
Equipment, whether Initial Inventory or otherwise, shall be lease to First
Recovery for five years. All leases to First Recovery shall be made pursuant to
this Agreement. First Recovery shall be obligated for all lease payment and all
other terms and conditions hereunder, regardless whether the Equipment is
subleased to its customers. First Recovery shall bear all credit or other
performance risk in connection with its customers. The effective date of the
lease of Initial Inventory shall be the date of which First Recovery receives
the Equipment and the effective date of the lease of all other Equipment shall
be the earlier to occur of (i) the date on which First Recovery subleases the
unit of Equipment to its customer, and (ii) thirty (30) days after First
Recovery receives the unit of Equipment. The units of Equipment that are leased
by Mansur to First Recovery, except the one hundred (100) units of Initial
Inventory, shall hereinafter be referred to as "the Leased Inventory".

                  1.5    Of the one hundred (100) units of Initial Inventory, 
ten (10) shall be shipped for delivery in August 1996, forty (40) shall be
shipped for delivery in September 1996 and fifty (50) shall be shipped for
delivery in October 1996 F.O.B. to a location designated by First Recovery.
Thereafter, unless the Agreement is terminated in accordance with its terms,
shipments of the Equipment to First Recovery shall be made in accordance with
the schedule set forth in Paragraph 1.3 by shipping F.O.B. to a location
designated by First Recovery. Any units of Equipment requested in excess of the
amounts set forth in Paragraph 1.3 shall be pursuant to purchase orders
submitted by First Recovery at least 90 days in advance of the requested
delivery date. Such additional requests will be subject to acceptance by Mansur,
provided that Mansur shall use its reasonable and best efforts to allocate up to
thirty-three percent (33%) of its total production to meet the requests of First
Recovery. If a notice of termination is given during the Term hereof, Mansur
shall not ship any units of Equipment during the period from the date notice of
termination is given to the date of termination.

                                       -2-



                  1.6    All Equipment shipped by Mansur to First Recovery shall
be new, clean and free of any parts washing solution.

                  1.7    Individual units of Equipment shall be tracked by both
parties by serial number to determine the location and lease status of each
individual unit. The parties shall reconcile such information at the end of
each calendar quarter.

                  1.8    First Recovery shall have the right, but not the
obligation, to place stickers or other identifying documentation with First
Recovery's trademarks or other company information on the Equipment, so long as
such identification has been approved by Mansur, such approval not to be
unreasonably withheld, and that such identification shall not obscure Mansur's
"System One" trademark or any other names and marks on the Equipment evidencing
Mansur's proprietary interests therein (or those of a third-party lease
financing company), or create any interest of First Recovery whatsoever in the
Equipment, other than as explicitly set forth herein.

                  1.9    Other than the solicitation and distribution rights set
forth herein, and its leasehold interest in the units of Equipment, First
Recovery has and shall have no rights whatsoever with respect to the Equipment
or Mansur's proprietary technology and trade secrets. If, in the course of its
performance hereunder, First Recovery acquires any confidential information with
respect to Mansur's Equipment, marketing plan, customers, or any other matter,
First Recovery shall maintain such information as strictly confidential, shall
not unitize or divulge such information in any way and, upon termination of this
Agreement, shall return or destroy all documents or records containing such
confidential information.

         2.       TERM.

                  This Agreement shall be for an initial term of thirteen (13)
months from the effective date set forth above (the "Term"), unless earlier
terminated pursuant to the provisions hereof. Either party may terminate this
Agreement with or without cause, upon sixty (60) days prior written notice to
the other party that this Agreement shall terminate.

         3.       TITLE RISK OF LOSS.

                  Title to the Equipment shall at all times remain in Mansur or
its assignee under any lease financing program. Risk of loss to each unit of the
Equipment shall pass to First Recovery for units that are in First Recovery's or
its customers' control and possession, upon First Recovery's receipt of the unit
of Equipment at First Recovery's designated facility as set forth in Paragraph
1.5. Risk of loss to the Equipment shall transfer back to Mansur for any units
that are returned to Mansur by First Recovery in accordance with the provisions
hereof at the time that the Equipment leaves First Recovery's control and
possession, so long as First Recovery has given reasonable notice of shipment
and shipment is by insured common carrier.

                                       -3-



         4.       TERRITORY.

                  For purposes of the pilot program as set forth in this
Agreement, and subject to the provisions of Paragraph 6.3 hereof, First
Recovery's marketing and distribution efforts related to the Equipment shall be
limited to the specific geographical territory identified on Exhibit C attached
hereto and incorporated herein by reference (the "Territory"). During the Term
hereof, Mansur shall refer all inquires relating to the Equipment from potential
customers in the Territory to First Recovery. Subject to the provisions of
Paragraph 6.3 with respect to certain options of First Recovery after the
expiration of the Term, First Recovery shall refer all inquiries with respect to
the Equipment from potential customers outside the Territory to Mansur, and
First Recovery shall lease no Equipment outside the Territory, and Mansur shall
lease no Equipment directly within the Territory.

         5.       SERVICE AND MAINTENANCE OF EQUIPMENT.

                  5.1    Once a unit of Equipment has been placed by First 
Recovery with a customer, First Recovery shall be responsible at its cost and
expense for providing service and maintenance for the Equipment. First Recovery
intends to supply the Equipment only with virgin mineral spirits purchased from
Ashland Chemical Company, a division of Ashland Inc., and Mansur shall ensure
that the Equipment shall be capable of using such product. Should any unit of
Equipment need replacement parts, Mansur shall promptly provide the needed
replacement part to First Recovery at Mansur's sole cost.

                  5.2    Mansur shall provide First Recovery with the necessary
technical training to enable First Recovery to service and maintain the
Equipment on a timely basis. Such training shall be at Mansur's sole cost, with
the exception of lodging and travel costs for personnel of First Recovery, which
shall be borne by First Recovery.

         6.       UNCONDITIONAL GUARANTEE/TERMINATION.

                  6.1    (a)    Mansur unconditionally warrants the Equipment as
follows:

                       MANUFACTURER'S UNCONDITIONAL WARRANTY
                  The Equipment specified herein is unconditionally warranted to
                  be fit for the purpose intended by the manufacturer for the
                  full term of the lease. The warranty shall cover all parts. If
                  the Equipment cannot be repaired within a reasonable period of
                  time, the manufacturer will immediately replace it with like
                  Equipment at no additional charge.

                                       -4-



                         (b)    First Recovery will provide the following 
service warranty to its customers:

                                   SERVICE GUARANTEE

                  First Recovery shall arrange for or provide all necessary 
                  maintenance and servicing of the Equipment, for the full term 
                  of the lease specified herein.

                         (c)    The warranty provided in Paragraph 6.1 is a 
limited warranty and does not apply to any products other than Equipment,
conditions resulting from improper use of the Equipment or operation of the
Equipment outside the specified environmental conditions, or conditions
resulting from modifications to Equipment other than modifications made by
Mansur. THE ABOVE WARRANTY IS THE EXCLUSIVE WARRANTY WITH RESPECT TO THE
EQUIPMENT, AND NO OTHER WARRANTY, EXPRESS OR IMPLIED, SHALL APPLY.

                  6.2    After the expiration or termination of this Agreement, 
if the parties do not enter into another agreement for the marketing and
distribution of the Equipment, First Recovery may, at its sole option, continue
to lease the Equipment it had leased to customers during the term hereof for the
remaining portion of the then current five (5) year term, as well as two (2)
optional successive renewal periods of five (5) years each; provided that each
renewal is made at then current prices (subject to the applicable discount from
current list price at which First Recovery is leasing units other than the
Initial as set forth in Exhibit B). During such lease period, Mansur shall
replace each unit of Leased Inventory at the end of each five (5) year lease or
renewal term, whichever is applicable, with the most recent development or
technological advancement of the relevant model of the Equipment. The replaced
unit shall be returned to Mansur and the list of inventory shall reflect the
Equipment change by serial number. If First Recovery exercises its right as set
forth above, then the terms and conditions of the Agreement shall survive
termination of this Agreement only as such terms and conditions relate to or are
applicable to the leased inventory. In the alternative, First Recovery may, at
its sole option, exercised by written notice within thirty (30) days of the
expiration or termination hereof, assign to Mansur all, but not less than all,
the leases for the Equipment that First Recovery has entered into with its
customers at the net present value of First Recovery's expected profit over the
remaining portion of the then current five (5) year term of such leases at a
twelve percent (12%) discount rate and return to Mansur all other Inventory and
all of First Recovery's leases with Mansur shall terminate without further
obligation by First Recovery. First Recovery may not assign to Mansur any lease
with respect to any unit of Equipment pursuant to which the First Recovery's
customer thereunder is obligated to pay First Recovery, on a monthly basis,
during the remaining term thereof, an amount lower than the amount First
Recovery is obligated to pay to Mansur, on a monthly basis, during the remaining
term of its lease with respect to such unit of Equipment.

                                       -5-


                        




                  6.3    After expiration or termination of this Agreement, if 
First Recovery has leased at least one thousand (1,000) units of Equipment
during the Term hereof, and First Recovery has not exercised the option set
forth in the next to last sentence of Paragraph 6.2, First Recovery shall have
the option, during a period of one (1) year after the expiration or termination
hereof (the "Option Period"), to lease a number of additional units of Equipment
from Mansur calculated as follows: for each unit of Equipment leased hereunder
by First Recovery prior to the notice of termination hereof, First Recovery
shall have the right to lease four (4) units of Equipment during the Option
Period for an initial five (5) year term, plus two (2) successive renewal
periods of five (5) years each at First Recovery's sole option. If First
Recovery chooses to exercise this option, First Recovery shall place the leased
units only at First Recovery customer locations anywhere in the contiguous
United States, but only if such locations were operated by customers of First
Recovery on the date of the expiration or termination of the Agreement. Since
Mansur may enter into exclusive agreements with other parties, First Recovery
shall not offer the units except as expressly provided hereby and the terms and
conditions of this Agreement shall survive termination of the Agreement only as
such terms and conditions relate to or are applicable to units of Equipment
placed in such locations.

         7.       EXCLUSIVITY.

                  During the Term of this Agreement, First Recovery shall have
the exclusive right to market and distribute the Equipment in the Territory.
Mansur shall market and distribute the Equipment directly to customers outside
the Territory. Mansur shall not enter into an agreement for distribution of
Equipment with any third party while this Agreement is in effect. For the
purposes of the preceding sentence, this Agreement shall not be deemed to be in
effect during periods of limited effectiveness as set forth in Section 6.2 and
6.3 hereof.

         8.       PATENT.

                  Mansur represents, warrants and covenants to First Recovery
that it owns a valid, existing and current patent on the Equipment, and that, to
the best of its knowledge, the design of the Equipment does not infringe upon
any rights of any third party. Mansur shall defend, indemnify and hold harmless
First Recovery, its parent, subsidiaries and affiliate corporations, and its and
their officers, directors, employees and agents (hereinafter referred to as the
"Indemnified Parties"), from and against any and all claims, liabilities, suits,
proceedings, judgments, orders, fines, penalties, damages, losses, costs and
expenses, including reasonable attorneys' fees, relating to the design of,
patentability of, or patent on the Equipment which any of the Indemnified
Parties may hereafter incur, become responsible for or pay cut as a result of
First Recovery's marketing and distribution of the Equipment, so long as First
Recovery provides Mansur with timely notice of, and an opportunity to defend any
claim that may give rise to an indemnification claim.



                                       -6-






         9.       INSURANCE

                  9.1    Without limiting, negating or reducing Mansur's
undertaking to indemnify, defend and hold harmless the Indemnified Parties as
set forth in Paragraph 8 or 11 of this Agreement, Mansur shall obtain and
continue in full force and effect throughout the term of this Agreement,
including any renewals, so long as such insurance is available on commercially
practicable terms, the following insurance coverage:


                  Products Liability           $5,000,000 per occurrence;
                                               $5,000,000 aggregate


                  9.2    The required insurance coverage shall be maintained 
with insurance companies qualified to provide coverage where business is
conducted pursuant to this Agreement, Mansur shall provide First Recovery with
thirty (30) days prior written notice of any change, modification or termination
in or of the above insurance coverages. If such change, modification or
termination results in insurance coverage that is unsatisfactory to First
Recovery, then First Recovery may terminate this Agreement immediately upon
written notice to Mansur, or, if satisfactory insurance can be maintained by
First Recovery at costs consistent with the costs previously acceptable to and
borne by Mansur, First Recovery may, with Mansur's prior consent, obtain such
insurance and be reimbursed therefor by Mansur. Upon request, Mansur shall
provide First Recovery with an insurance certificate evidencing the required
coverages and naming First Recovery as an additional insured.

        10.       REPRESENTATIONS AND WARRANTIES.

                  10.1   Mansur represents, warrants and covenants to First

                  Each party is and shall remain an independent contractor in
